The FBI has ordered a Florida medical examiner’s office not to release the autopsy report of a Chechen man who was killed during an FBI interview in May over his ties to one of the suspected Boston Marathon bombers.

The autopsy report for Ibragim Todashev, 27, killed by an FBI agent during an interrogation which
took place in his apartment on May 22 was ready for release on
July 8. However, the FBI barred its publication, saying an
internal probe into his death is ongoing.

“The FBI has informed this office that the case is still
under active investigation and thus not to release the
document,” according to statement by Tony Miranda, forensic
records coordinator for Orange and Osceola counties in Orlando.

The forensic report was expected to clarify the circumstances of
Todashev's death.The Bureau’s statement issued on the day of the
incident provided no details of what transpired, saying only that
the person being interviewed was killed when a “violent
confrontation was initiated by the individual.”

Back in May Ibragim Todashev’s father showed pictures of his dead son’s body at a press
conference in Moscow, revealing he had been shot six times.

"I only saw things like that in movies: shooting a person,
and then the kill shot. Six shots in the body, one of them in the
head,” Abdulbaki Todashev said .

The medical examiner's office promised to check on a monthly
basis whether the FBI is ready to grant permission for release of
the autopsy report.

Todashev was interrogated by the FBI several times following the
Boston Marathon bombings, with the final interview resulting in a
fatal altercation. He was supposedly questioned over his alleged
role in an unsolved 2011 triple homicide in Waltham,
Massachusetts, which bombing suspects Tamerlan and Dzhokhar
Tsarnaev have been implicated in. Todashev was reportedly about
to sign a written statement which would have tied him to the
murders when he allegedly attacked an FBI agent.

Investigators, most of them speaking anonymously, would later
offer conflicting accounts of what happened in Todashev’s final
minutes, with some claiming the man brandished a knife and others
insisting he was unarmed.

Despite the FBI’s promise to look into the case, civil rights
activists have called for an independent investigation.

The US Department of Justice Civil Rights Division announced on
Monday it was overseeing a federal inquiry into the shooting
incident.

“Federal prosecutors will review the evidence and make an
independent determination whether a federal criminal
investigation is warranted,” the Boston Herald cites a
letter by US Deputy Assistant Attorney General Roy L. Austin as
saying.
